Standalone Caching Utilities

ocache is a JavaScript/TypeScript library providing robust caching utilities for functions and HTTP handlers. It supports common caching strategies such as time-to-live (TTL), stale-while-revalidate (SWR), and multi-tier caching. Currently at version 0.1.4, it is under active development by the unjs organization, suggesting a focus on modularity and integration within their ecosystem, although it is designed to be standalone. Key differentiators include built-in request deduplication for cached functions, automatic HTTP response caching with `etag` and `last-modified` support, and a flexible multi-tier caching mechanism that allows for layered cache storage. The project appears to follow a rapid release cadence for minor enhancements and performance improvements, typical for libraries in their early 0.x development phase, with type definitions included for TypeScript users.
